I am using windows 8.1. From a few days I am unable to access command prompt and power shell form the file menu in file explorer. That option is unavailable. Please refer the screenshot.

Please help me out. I've tried system restore that also doesn't works. It says please disable your antivirus even though I have windows defender(the only anti virus app i am running) and i have turned is off.

D: might have permission issues, did you upgrade from 7/8? Might want to backup your data, format it and recover your data, BUT, I know there is likely a better option someone will post soon enough so I'd wait

Well I don't think D has permission issues BTW it doesn't works for any drive or any folder.
